Sauerland takes aim at Klitschko

WBA/IBF/WBO/IBO heavyweight champion Wladimir Klitschko could be facing a steady diet of Team Sauerland fighters in 2013 as the German promotional firm has a lock on the mandatory position in the WBA, IBF and WBO. Wlad’s mandatory challenger in the WBA is Alexander Povetkin, the WBA “regular champion. Kubrat Pulev is rated #1 by the IBF and Robert Helenius has leap-frogged into the WBO’s #1 slot from the #13 position after his decision win over Sherman “Tank” Williams. The IBO doesn’t require mandatory defenses.
